Answer:
Step-by-step explanation:
take two points to find the equation:
(0,4),(-2,0)
y= 2x+4
domain is where the equation is defined ( x inputs)
Range is the set of values that correspond with the domain(y outputs)
the domain and the range are all real number
domain(-∞,∞) , range (-∞,∞)
Answer:
2.56
Step-by-step explanation:
14.7 - 1.9 = 12.8
12.8/5 (sides) =
n = 2.56
check:
2.56 * 5 = 12.8
12.8 + 1.9 = 14.7
Answer:
17
Step-by-step explanation:
add the exponents
Answer:
no
Step-by-step explanation:
because they have different gradients
Answer: Assuming the riders starts at the position (20, 0) on the x-axis, the exact position of the rider will be (20cos75, 20sin75) or about (5.18, 19.32).
The angle for 5pi/12 radians is 75 degrees. Therefore, to find the position we can use the sine and cosine of 75 to find the x and y value of the coordinate.
For the y-value, we can write and solve:
sin75 = x/20
For the x-value, we can write and solve:
cos75 = x/20
